TOBACCO-PIPE AND CIGAR-HOLDER.

special reference to improvements in the" mouth pieces thereof. I

Pipes and holders are objected to by most smokers because of the unpleasant efiect of the smoke on the tongue and roof of the mouth. This effect or biting is commonly supposed to be caused by the unexplainedmanner in which. tobacco burns in a pipe or holder, as contrasted with the free burning of a cigar; and is often attributed to the quality of the tobacco, particularly to kinds that burn more hotly than others. I conceive that neither explanation is correct;

and that, instead of being an unavoidable incide'nt of the smoking of tobacco in pipes and holders, the burning or biting eifect is due to the improper construction of the bit, stems, or mouth pieces.

Toprevent the too rapid" burning of the tobacco, the duct leading from the bowl and opening through the mouth piece of a pipe or holder, is made very small, in proportlon to the size of the bowl; and it is now clear to me that the objectionable biting is caused by the constriction, and consequently velocity, of the smoke in the small duct and the accompanying concentration and d1rect impingement of the hot smoke upon the tongue or the roof'of the mouth. Froceeding on this conception and observation, and with the distinct purpose of lessening and obviating. the biting effect, I, form the stemor mouth piece in such manner that the velocity of the smoke leaving the bowl is reduced before the smoke emerges from the mouth piece and the stream of smoke, instead of being concentrated and emitted at one point, is sub-divided and pleasantly difi'u'sed in the 'mouth. 4

Myinvention will be readily understood upon reference to the drawingsthat form a part ,of this specification, in whlch I have exhibited my invention In the form that I prefer. 0

mouth piece embodying my invention Fig. 2 shows a modified form of the mouth piece in which the smoke duct opens through the top ;Fig. 3 is an enlarged longitudinal section of the pipe stem or piece shown in Fig. 1;Fig. 4 is a longitudinal section of my invention in the form of a cigar or cigarette holder ;Fig. 5' is a cross section on the line 5-5 of Fig. 3 ;.'Fig. 6 is a cross section on the line 66 of Fig. 3 Fig. 7 is a cross sectionon the line*7-7 of Fig. 3;-Fig. 8 is an end view of the mouth piece ;Fig. 9 is an end elevation of the stem shown in Fig. 1.

No attempt is made to show more than typical forms of my invention, for it is obvious that any skilful pipe maker can readily apply the invention in man forms; and, to a great variety of .pipes an holders.

The tobacco pipe shown in Fig Land the cigar'holder in Fig. 4, are of familiar shapes. They differ from others only in the form and arrangement of their smoke ducts. The bowl, A, of the pipe is shown by dotted lines in Fig, 1; and the bowl, B, .of the holder clearly appears in full lines in Fig. 4. The smoke ducts of the pipe and the holder are the same, except as they are "affected by the differing lengths thereof.

proper, C, in direct communication with the bowl ;a preferably triangular ductenlargement or chamber, D, that receives the smoke from the portion, C; -and, three separate ducts, E, E, E, which lead from said chamber, D, and all of which open through the end, F, of the mouth piece or bit. The ducts, E, may open straight through the end, F, as shown in Fig. 1, or they may open through the top of the bit, as shown in Fig. 2. I prefer the straight ducts of Figs. 1, 3 and 4 to the bent ducts of Fig. 2 because the straight ducts fully serve the purpose, and may be cleaned more easily. The portion, C, of the smoke duct is of the usual size of the corresponding duct in an ordinary pipe stem or cigar holder. Its size determines the draft; which is a factor that has been nicely determined in the past, and which I prefer not to disturb or modify. Because of the constricting or choking effect of the portion, 0, of the smoke duct, I term it the choke or choke portion of 1 viously the smoke is exhausted from the exthe mouthpiece. When smoke emergesfrom the choke and enters the portion, D, 1't expands. Thus its velocity is diminished;

and, some of the heat is there dissipated. For these reasons the term expansion chamher is appropriate to the portion, D. Ob-

pansion chamber by way of the several diverging or difiusing ducts, E. .It follows that the smoke leaves the ducts, E, at greatly diminished velocity and at quite Widely separated points. In this way I effectively disv sipate a portion of the heat; reduce the velocity of the smoke entering the mouth lessen the impact thereof upon the tongue or Walls of the mouth; and also widely diffuse the smoke; thereby overcoming and doing away with the ill effects sufi'ered in the use of ordinary pipes or holders. It is best to form this smoke duct by drilling or molding the stem. *In either case I prefer to employ drills, or several mold cores, which are straight, as opposed to curved,

.and may be withdrawn easily. By making the ducts, O, and, E, in this manner the in advantageously provided in the mouth piece, but I observe that most mouth pieces are fiat and I find that either two or three diverging ducts in the same horizontal plane best serve the I purpose and yet may be formed Without materially reducing the strength of the bitat the point 'where it is apt to be crushed by the teeth of the smoker. The importance of the dividing Walls, struts, or partitions, E, between the ducts, E, should be noted in this connection.

The expansion chamber, D, (well shown in Fig. 7) does not require such struts because it is beyond the reach of the smokers teeth.

Having thus described my invention, I claim as new and desireto secure by Letters Patent:

1. The herein' described improvement, comprising asmokers mouth piece having a smoke duct composed of a choke and a plurality of'difi'usion ducts that converge therein and form an intermediate expansion chamber.

2. The herein described improvement, comprising a smokers mouth piece containing a smoke duct that is choked adjacent the bowl and which terminates in several branches, each of the same size as the choke,

and all opening through the other end of the mouth piece.

In testimony whereof, I have hereunto set my hand this 7th day of October, 1915.
